Document Type and Number:
WIPO Patent Application WO/2020/262660
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a spectacle lens, the spectacle lens being a cured material formed by curing a polymerizable composition including 5-(isocyanatomethyl)bicyclo[2.2.1]hepto-2-ene and one or more polythiol compounds, said method including: preparing the polymerizable composition by a preparation step which includes a first mixing stage for mixing 5-(isocyanatomethyl)bicyclo[2.2.1]hepto-2-ene and a polythiol compound in the presence of a first catalyst for catalyzing the thiol-ene reaction, and a second mixing stage for mixing a second catalyst for catalyzing a thiourethanization reaction with the mixture obtained from the first mixing stage; and curing the polymerizable composition.
